64 Barracuda rear end
Mark, do you remember the thread just a short while ago from the member from Germany?? He was having a problem getting his 14x5.5" rims OK'd by the safety police??
Someone in that thread posted a 1965 option and package code document listing the available options and what features and options were available in certain packages. In those documents I believe it had the 8 3/4" as an option as well as the rim sizes the OP was looking for.
Good read that bit of info, I'm going to look back through the threads and see if I can come up with that post!! Geof
